Fault Tolerant Smart Transformer in Distributed Energy Systems

Inhalt:
The fast development of distributed generation systems (DGS), including increasing number of the renewable energy sources (RES) demand the change of classical grid into smart grids (SG) integrating all new distributed elements e.g. active loads/sources/energy storages. Currently used conventional transformer cannot fulfil all requirements of SG and therefore new solution is demanded due to the nature of extremely different types of energy sources, loads and frequent voltage disturbances occurring in DGS. The proposed modern solution is the application of multifunctional power electronics fault tolerant Smart Transformer (ST) that is able to not only meet main requirements of SG, but also respond to the future challenges, defined by the constant progress of technology in all new fields (e.g. electromobility, energy store systems etc.).
